This practically oriented book illustrates and reviews the imaging appearances of the common and unusual complications that may occur after upper gastrointestinal endoscopy, endoscopic retrograde cholangiopancreatography (ERCP), colonoscopy, polypectomy, stricture dilatation, and stent placement.Detailed attention is devoted to the assessment of complications after percutaneous endoscopic gastrostomy (PEG) positioning, the issues associated with video capsule retention after small bowel capsule endoscopy, and iatrogenic colonic perforations in patients with inflammatory bowel diseases. A dedicated chapter explains the expanding role and possibilities of interventional radiology in the treatment of such complications. The pivotal role of multidetector computed tomography (CT) in the detection and grading of endoscopy-specific iatrogenic complications is highlighted. In addition, normal imaging appearances are presented for comparison and information is provided on such aspects as the mechanisms of complications, patient- and procedure-related risk factors, clinical features, and treatment options according to established guidelines.The book will be invaluable in enabling gastroenterologists, general surgeons, and radiologists to diagnose and treat endoscopy-related complications in timely fashion.
